Visual score for susceptibility artifacts for ASL-CBF and DSC-MRI maps (rCBF and rCBV). 1 = no susceptibility artifacts, 2 = small/moderate (maximum diameter <2 cm) susceptibility artifacts, not affecting imaging evaluation, 3 = extensive susceptibility artifacts (maximum diameter >2 cm), deteriorating imaging evaluation. ASL-CBF = arterial spin labeling- cerebral blood flow; DSC-MRI = dynamic susceptibility contrast perfusion magnetic resonance imaging; rCBF = relative cerebral blood flow; rCBV = relative cerebral blood volume.
